Abstract

The thermal treatment have been combined with MRI which is able to acquire both an anatomical image with high-contrast and a thermal image, and have recently used for removing the tumor effectively. This study is to make a patch antenna which is designed to operate at 2.45GHz that has compatibility with MRI. The characteristic and specific absorption rate(SAR) were confirmed using computer simulation and confirmed a possibility of hyperthermia by performing experiment.

최근 열 치료법은 종양을 효율적으로 제거하는 방법으로 높은 해부학적 영상 대조도와 온도영상이 가능한 MRI와 결합하여 사용되고 있다. 본 연구는 2.45GHz에서 동작하도록 개발된 MR 호환 가능한 초고주파 평판 가열 안테나를 개발 및 성능평가에 대한 연구이다. 컴퓨터 모의실험을 통하여 평판 가열 안테나의 특성 및 전자파 인체 흡수율(SAR)을 확인하고, 가열실험을 수행함으로써 제작된 안테나의 열 치료 적용 가능성을 확인할 수 있었다.
